6d6b3e911c Add variants of digest() and hmac() that accept text inputs.
Marko Kreen says:
This is so obvious that I would like to make it 'official'.

Seems like the theology around bytea<>text casting kept me from
seeing the simple :)

cff23429d6 I noticed that the contrib Makefiles were reorganized.
Converted pgcrypto one too.

* Changed default randomness source to libc random()
  That way pgcrypto does not have any external dependencies
  and should work everywhere.
* Re-enabled pgcrypto build in contrib/makefile
* contrib/README update - there is more stuff than
  only 'hash functions'
* Noted the libc random fact in README.pgcrypto

ab56022864 Big thanks to Solar Designer who pointed out a bug in bcrypt
salt generation code.  He also urged using better random source
and making possible to choose using bcrypt and xdes rounds more
easily.  So, here's patch:

* For all salt generation, use Solar Designer's own code.  This
  is mostly due fact that his code is more fit for get_random_bytes()
  style interface.
* New function: gen_salt(type, rounds).  This lets specify iteration
  count for algorithm.
* random.c: px_get_random_bytes() function.
  Supported randomness soure: /dev/urandom, OpenSSL PRNG, libc random()
  Default: /dev/urandom.
* Draft description of C API for pgcrypto functions.

New files: API, crypt-gensalt.c, random.c

2518e27334 /contrib/pgcrypto:
* remove support for encode() as it is in main tree now
* remove krb5.c
* new 'PX library' architecture
* remove BSD license from my code to let the general
  PostgreSQL one to apply
* md5, sha1: ANSIfy, use const where appropriate
* various other formatting and clarity changes
* hmac()
* UN*X-like crypt() - system or internal crypt
* Internal crypt: DES, Extended DES, MD5, Blowfish
  crypt-des.c, crypt-md5.c from FreeBSD
  crypt-blowfish.c from Solar Designer
* gen_salt() for crypt() -  Blowfish, MD5, DES, Extended DES
* encrypt(), decrypt(), encrypt_iv(), decrypt_iv()
* Cipher support in mhash.c, openssl.c
* internal: Blowfish, Rijndael-128 ciphers
* blf.[ch], rijndael.[ch] from OpenBSD
* there will be generated file rijndael-tbl.inc.

cb5427ee47 I would like to do a interface change in pgcrypto. (Good
timing, I know :))  At the moment the digest() function returns
hexadecimal coded hash, but I want it to return pure binary.  I
have also included functions encode() and decode() which support
'base64' and 'hex' encodings, so if anyone needs digest() in hex
he can do encode(digest(...), 'hex').

Main reason for it is "to do one thing and do it well" :)

Another reason is if someone needs really lot of digesting, in
the end he wants to store the binary not the hexadecimal result.
It is really silly to convert it to hex then back to binary
again.  As I said if someone needs hex he can get it.

Well, and the real reason that I am doing encrypt()/decrypt()
functions and _they_ return binary.  For testing I like to see
it in hex occasionally, but it is really wrong to let them
return hex.  Only now it caught my eye that hex-coding in
digest() is wrong.  When doing digest() I thought about 'common
case' but hacking with psql is probably _not_ the common case :)

5bb2300b59 Revise handling of oldstyle/newstyle functions per recent discussions
in pghackers list.  Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention.  pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'.  A newstyle function must be identified
by an associated info routine.  See src/backend/utils/fmgr/README.
